Scotch 6.0.6 is mostly a bugfix version. It provides some new minor features, such as the handling of disconnected components for sparse matrix ordering, which may prove useful in some cases, and full-featured LZMA (de)compression.pelegrin@users.gforge.inria.fr (Francois PELLEGRINI)Tue, 31 Jul 2018 07:55:24 GMThttps://gforge.inria.fr/forum/forum.php?forum_id=11530https://gforge.inria.fr/forum/forum.php?forum_id=11530Scotch 6.0.5 is out !https://gforge.inria.fr/forum/forum.php?forum_id=11525
It provides bugfixes as well as new features, such as the ability to map onto potentially disconnected pieces of a given target architecture (e.g., a set of nodes of a large parallel computer, assigned by a batch scheduler).pelegrin@users.gforge.inria.fr (Francois PELLEGRINI)Thu, 15 Feb 2018 07:22:36 GMThttps://gforge.inria.fr/forum/forum.php?forum_id=11525https://gforge.inria.fr/forum/forum.php?forum_id=11525Scotch 6.0.4 is out!https://gforge.inria.fr/forum/forum.php?forum_id=11428

This is a minor revision version. It provides two new methods: SCOTCH_free() and SCOTCH_numSizeof().pelegrin@users.gforge.inria.fr (Francois PELLEGRINI)Tue, 23 Sep 2014 17:40:58 GMThttps://gforge.inria.fr/forum/forum.php?forum_id=11408https://gforge.inria.fr/forum/forum.php?forum_id=11408Release 6.0.1 of Scotch is out !https://gforge.inria.fr/forum/forum.php?forum_id=11406
Almost two years after the release of the 6.0.0 branch, revision 6.0.1 has been released. While it is technically a bugfix release, with no apparent new features, much has changed &quot;under the hood&quot;. # Algorithms for repartitioning and (re)partitioning with fixed vertices have been improved. # Multithreading issues have been solved. # From now on, there is no separate &quot;*_esmumps&quot; version. The additional libraries for MUMPS can be generated by running &quot;make esmumps&quot; for the sequential libraries and &quot;make ptesmumps&quot; for the parallel libraries.pelegrin@users.gforge.inria.fr (Francois PELLEGRINI)Sat, 20 Sep 2014 20:36:07 GMThttps://gforge.inria.fr/forum/forum.php?forum_id=11406https://gforge.inria.fr/forum/forum.php?forum_id=11406The &quot;20 y.o. Scotch&quot; edition, aka version 6.0, is out !https://gforge.inria.fr/forum/forum.php?forum_id=11238
20 years ago, the first line of Scotch was written !<br />
Version 6.0 is a major update, which comprises many new features, both at the algorithmic and programming levels.pelegrin@users.gforge.inria.fr (Francois PELLEGRINI)Sat, 01 Dec 2012 23:49:19 GMThttps://gforge.inria.fr/forum/forum.php?forum_id=11238https://gforge.inria.fr/forum/forum.php?forum_id=11238Scotch 5.1.12 is out!https://gforge.inria.fr/forum/forum.php?forum_id=9932
Release 5.1.12 is mainly a bugfix release. In particular, load balance enforcement has been improved for parallel graph partitioning. It also comprises some new features : # The clustering features of Scotch and PT-Scotch are now available through the '-q' option of command line programs dgmap, dgpart, gmap and gpart. # Strategy string building helper routines are also available for clustering in the libScotch library. # Some internal graph handling routines have been exposed in the interface, such as for graph coarsening.pelegrin@users.gforge.inria.fr (Francois PELLEGRINI)Thu, 01 Sep 2011 00:50:15 GMThttps://gforge.inria.fr/forum/forum.php?forum_id=9932https://gforge.inria.fr/forum/forum.php?forum_id=9932Scotch 5.1.11 is out!https://gforge.inria.fr/forum/forum.php?forum_id=8691
We announce the release, as libre/free software, of revision 5.1.11 of the SCOTCH and PT-SCOTCH software package and library for sequential and<br />
parallel graph partitioning, sequential mesh/hypergraph partitioning and static mapping, and sequential and parallel sparse matrix block ordering.<br />
<br />
This is is mainly a bugfix release. Yet, it also comprises new features :<br />
<br />
- New C routines allow users to dynamically allocate Scotch opaque objects, so that executables are less dependent of dynamic library upgrades.<br />
<br />
- A new routine allows users to know what release of the library they are currently linked with.<br />

Scotch and PT-Scotch are now fully 64-bit. PT-Scotch 5.1.10 has been able to bipartition a graph of more than 2.4 billion vertices, distributed across 2048 processors, on machine Platine of French CCRT computer center, in a bit more than a minute. Weak scalability experiments were carried out up to 8192 processors on machine Hera at LLNL.<br />
<br />
PT-Scotch now has improved load balance capabilities, which allow it to enforce almost exact load balance across domains whenever requested.<br />
<br />
New command-line and library options allow users to tailor easily their strategies according to their needs: quality, speed, scalability, load<br />
balance, etc.<br />
